Excavating shovel



Feb. 11, 1930. J. w. PAGE EXCAVATING SHOVEL Filed Nov. 14, 1928 Patented Feb. 11, 1930 UNITED STATES- JOHN W. PAGE, OF CHICAGO, ILLINOIS EXCAVA'IING SHOVEL Application filed November 14, 1928. Serial No. 319,378.

In the operation of the bucket, it is difiicult or impossible to always cause a bucket to drop absolutely straight so that the front edges will engage the ground exactly at right angles. \Vhenever the bucket, when so being dropped,

is tipped slightly to one side, it will be seen that there is a tendency to bend the leading front edge of the side wall inwardly as the same engages the ground.

One of the features of my invention is the Z0 provision of means to prevent or lessen such inward bending of the front edges of the side walls of such a bucket. Another feature of my invention is the provision of means for increasing the amount of load taken into the bucket during the scraping operation. My

invention also provides means for attaching the loading or hauling line.

Other features and advantages of my 1nvention will appear morefully as I proceed with my specification.

In that form of device embodying the features of my invention shown in the accompanying drawings, Fig. 1 is a view in perspective; Fig. 2 is a view taken as indicated by IS the line 2 of Fig. 1; Fig. 3 is a view taken as indicated by the line 3 of Fig. 2; and Fig.

4 is a view similar fied form.

-As shown in the drawings, at is the body of to Fig. 2 showing a modi- 0 the bucket, such as is well known in the art and is familiar to excavation engineers under the name of the Page bucket. The bucket is pivotally supported by a bail 5, usually of chain, which is in turn carried by a hoisting 5 rope 6. 7 is the rear end of the loading or hauling line. 8 is the characteristic holding line, forming a part of what is now known as the Page hitch, the same running over tions of the line 7 also forming a part of the Page hitch, the two parts running. in accordance' with common practice, to opposite front edges of the side walls of the bucket.

The front bottom corners of the side walls 12 of the bucket are cut back, as indicated by 12, so that the teeth 13 on the forward edge of the bottom of the bucket ordinarily lie somewhat behind the front edges 12 of the side walls of the bucket. Accordingly, when the bucket is allowed to fall on its nose or front end, the front edges of the side walls ordinarily strike first and may be bent inwardly by contact with the ground unless means are provided to prevent the same.

It is customary to provide a hitch-plate at the forward edges of the side walls of the bucket for attaching the ends 10 of the hauling line. In the preferred form of device shown in Figs. 1, 2 and 3, I provide a combination hitch-plate and bumper member, forming such hitch-plate so that the same projects in front of the front edge of the side wall and is offset outwardly therefrom. When'thus made, the hitch-plate also acts as a bumper member and being offset outwardly from the front edge 12 of the side Wall. When the same engagesthe ground, even though the' bucket is turned at somewhat of an angle, the force against the bumper member tends to pull the front edge of the side wall outwardly, thus preventing or lessening any inward bending.

The construction referred to is shown quite clearly in the drawings where 12 indicates a, side wall and 12 the front edge thereof. 15 indicates the bumper member which is shown in Figs. 1, 2 and 3 as also being a hitch-plate. This bumper member 15 issuitably fastened to the side wall 12 by means of rivets 17 and is preferably formed with a recess 15 to accommodate the forward edge of the side wall 1 that, asshown in Figs. 2 and: 4,theinner sur-' I Y a sheave 9 and being attached to the front of D the bucket. 10 designates the two continuaface of the wall is above. :That'is, the'ofiset of the end 15* from the plane of the wall12',"

as shown downwardly in Fig. 2, indicates an outward offset with respect to the inside of the bucket.

In the preferred form shown in Figs. 1 2

and 3, the bumper member 15 is provided at its 4 forward end with a vertical hole 15 adapted to accommodate a pin 18 passing through the eyes of a clevis 20 to which is attached the chain 10.

The device shown in Fig. 4 is similar to that shown in Figs.l, 2 and 3, except that the bumper member 115, which is attached to the side wall 112, is not used as a hitch-plate, the ordinary hitch-plate 116 with the eye 116 being provided for the purpose of retaining a pin to hold the clevis 20. It will be seen also that since the bumper members, as shown in the preferred form, are

.oflset outwardly from the side walls, they serve to increase the load taken by the bucket when it is drawn forward.

While I have shown and described certain embodiment of my invention, it is to be understood that it is capable of many modifications. Changes, therefore, in the construction and arrangement may be made without departing from the spirit and scope of the invention as disclosed in the appended claims,

in which it is my intention to claim all novelty inherent in my invention as broadly as possible, in view of the prior art.

What I regard as new, and desire to secure by Letters Patent, is: v v

1. An excavating shovel of the character described, having side walls, and bumper members attached to-saidside walls, the front ends of said bumper members projecting in front of the front edges of said side walls and offsft outwardly from the planes of said side wa s.

2. A shovel provided with bumper menr- V bers as claimed in claim 1, .in which said bumper members are provided with means for securing the ends of a hauling line thereto.

3. A shovel as claimed in claim 1, in which the bumper members are provided with means at their forward ends for securing the ends of a hauling line thereto.

4. An excavating shovel of the character described, having side walls, and combinedbumper and hitch-plate members attached to said side walls, the front ends of sai mem bers projecting in front of the front edges of said side walls and offset outwardly from the planes of said side walls.

5. An excavating shovel of the character described, having side walls, and bumper -members attached to said side walls, the front ends of said bumper members offset outwardly from the planes of said side walls.

6. An excavating shovel provided with bumper members as claimed in claim 5, in which the bumper members are provided with means for securing the ends of a hauling line being provided with vertical openings to ac-- commodate clevis-retaining pins.

9. An excavating shovel of the character described, having side walls, and combined bumper and hitch-plate members attached to said side walls, the front ends of said mem bers being oflset outwardly from the planes of said side walls. I

10. An excavating shovel of the character described, having side walls, and bumper members attached to saidside walls at or near the front edges thereof, the front ends of said bumper members offset outwardly from the planes of said side walls.

- In testimony whereof, I have hereunto set my hand this 12th day of November, 1928.
